st: find-replace in stata

hi, I have a fairly simple problem for which I am sure STATA has an
easy solution but I can't seem to find it. I am hoping you can help
me.
Here is what I need to do:
I have a string variable called company_name which has names like
"microsoft ltd."
What I need to do somehow remove the dot at the end of the "ltd." in
all cases where a dot appears at the end of the ltd. The equivalent
in excel is a global find-replace. I tried "recode" but that seems to
work only for numeric variables.
How do I do this?
thanks in advance for your help. I appreciate it.
